Lupinus plant named ‘Red Rum’

ABSTRACT

‘Red Rum’ is a new variety of  Lupinus hybridus  that exhibits numerous and large-shaped red-colored flowers.

Botanical classification: Lupinus hybridus.

Varietal denomination: ‘Red Rum’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Lupinus hybridus known by the varietal name ‘Red Rum’. The new variety was developed in Great Britain. The new variety is a result of cross breeding Russell Hybrid Lupinus Seedling #WCL 027/96 (female parent) (unpatented) and an unknown Lupinus male parent (unpatented). The purpose of the breeding program was to develop a cultivar that exhibited improved color, habit, and bloom form from other Lupinus varieties known to the breeder. The new variety is similar in growth habit to its female parent, but differs in flower color. The new variety is similar in flower color to Lupinus hybridus ‘My Castle’, but differs in flower size, growth habit, and the closeness of the flowers packed on a spike. The new variety was first asexually reproduced by basal cuttings/tissue culture in Great Britain. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive asexual propagations. Characteristics that distinguish the new variety from others known to the breeder include:

-   -   • Clear and intense flower color;     -   • Flower form — papilionaceous, with large flowers packed         closely on the flower spike; and     -   • Vigorous growth habit.

The new variety was grown in open soil with additional organic fertilizer applied. The new variety initiates and develops roots in 21 days at 15° C. A finished and flowering plant is produced in 36 weeks in a 21 cm container. The new variety exhibits sparse, but thick roots, that exhibit some branching.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 is a photographic image of multiple plants of the new variety; and

FIG. 2 is a close-up photograph of the petals of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions carried out in Great Britain. The color readings were taken outside under natural daylight. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
